PNEUMATIC WATER-ELEVATOR.

comer. a

To all whom it may concern:

Be it known that I, VERNoR L. ELLISON, a citizen of the United States, residing at Shawnee, in the county of Pottawatomie and State of Oklahoma, have invented new and useful Improvements in Pneumatic \Vater- Elevators, of which the following is a specification.

This invention provides novel means for elevating water from wells, springs or other sources and aims to utilize pneumatic pressure as the medium for compelling the water to rise to the required elevation and to discharge when an outlet is opened.

The invention contemplates a submerged tank having a valve controlled inlet which automatically closes under pressure from within the tank and opens when said pressure is relieved to admit water passing from the well, spring or other source into the tank. A reservoir containing air under pressure has valved communication with the water reservoir so as to exert a pressure upon the water contained therein to insure discharge thereof at the outlet of the supply pipe when said outlet is opened. Combined with the air reservoir is means for charging the same with air under pressure, a vent for relieving the pressure and a'gage to determine the pressure of the charge.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claim.

Referring to the drawings, forming a part of the specification, Figure 1 is a detail view, showing a pneumatic water elevating mechanism embodying the invention. Fig. 2 is a partial sectional view. Fig. 3 is a detail view of the valved outlet between the air and water reservoirs. Fig. 1 is a detail horizontal section of the valve mechanism between the two chambers of the tank. Fig. 5 is a view similar to Fig. 1, showing the relation of the parts when the movable casing is turned to throw the openings out of register.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings, by the same reference characters.

A tank 1 is provided and is subdivided by means of a partition 2 to provide chambers 3 and 1 which constitute reservoirs, the for Specification of Letters Patent.

mer for air, the latter for water. The reservoir 1 has a valve controlled opening 5 in its bottom which admits water passing from the well, spring or other source into the reservoir when the air vent connected therewith is open, said valve automatically closing when the pressure within the reservoir exceeds the external pressure, thereby preventing escape of the confined water. A discharge pipe 6 extends to within a short distance of the bottom of the reservoir 1 and preferably passes through the tank, although such arrangement is not essential. The supply pipe 6 may lead to any point and connect with the surface pipe of a dwelling or other structure and is provided with the usual valve controlled outlets for drawing off water when required. The partition 2 has an opening which is surrounded by a collar 7, which is internally screwthreaded. A casing 8 is connected to the collar 7 and has an opening 9 in a side thereof. A casing 10 is fitted within the casing 8 and is connected to a pipe 11 which constitutes a vent. The casing 10 has an opening 12 which is adapted to register with the opening 9 and thereby establishing communication between the two reservoirs 3 and 1 so that the air may pass from the reservoir 3 into the reservoir 1 and exert a pressure upon the water contained therein. The casing 10 has a limited movement to throw the openings 9 and 12 into or out of register. A pin 13 projecting from one casing is adapted to enter a recess in the other casing to limit the relative movement of the two casings. The vent pipe 11 extends through the reservoir 3 and is provided at its upper end with a valve 11, which when opened relieves the reservoir 1 of all pressure and admits of water passing from the well into the reservoir, the displaced air escaping through the vent pipe 11. The valve 11 serves as a handle to turn the vent pipe 11, which latter has the movable casing 10 attached thereto.

An air compressor 15 of any make or design has connection with a reservoir 3 to supply the same with air under pressure. A gage 16 is connected with the reservoir 3 to indicate the air pressure.

In the installation of the apparatus the tank is placed so that the reservoir 1 is submerged in the water and upon opening the vent the water passes from the well or other source into the reservoir 1, the valve 5 being opened by the pressure of the water from without. The displaced air escapes through the vent 11. After the reservoir has received a supply of water the vent is closed and communication established between the air reservoir 3 and the water reservoir 4 thereby permitting compressed air from the reservoir 3 passing into the reservoir at and exerting a downward pressure upon the water contained therein. Upon opening any outlet connected with the pipe 6 the water flows therefrom, the pressure of air upon the water in the reservoir serving to expel the water therefrom. The reservoir 3 is charged with air by the air pump or compressor 15.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which "the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.

Having thus described the invention What is claimed as new, is

ater elevating means comprising a tank having a 'alve controlled opening in its hottom and subdivided by a partition to form air and water reservoirs, casings mounted upon said partition and having openings, one of the casings being fixed and the other movable, a vent pipe connected With the movable casing, a valve at the upper end of the vent pipe serving to provide a handle for turning the vent pipe and the casing connected therewith, a discharge pipe extending through the tank and terminating within a short distance of the bottom of the water reservoir, and means for charging the air reservoir with air under pressure.

In testimony whereof I affix my signature in presence of two witnesses.
